– the NVRAM will retain unlocks.
Namco designed Tekken 3 with an internal clock and counter system to keep the game fresh for arcade operators and players. 1. The Time-Release Character System
| Problem | Symptoms | Solution | |---------|----------|----------| | | MAME does not save any NVRAM data; changes are lost on restart. | Manually create a folder named nvram in your MAME root directory. Some older versions required this manual step. | | NVRAM file size mismatch | Unlocks appear not to work, or the game behaves strangely. | Delete the existing tekken3.nv , run the game once to generate a fresh file, then replace it with a compatible unlock file. | | Battery failure (real hardware) | Arcade cabinet loses all unlocked characters and settings after being powered off for a while. | Replace the battery on the System 12 PCB. After replacement, you must either wait ten weeks for characters to unlock again or use a service menu cheat. | | “First Power On” message every launch | Emulator always thinks it is the first boot, ignoring saved NVRAM. | Check that your MAME or ZiNc configuration has NVRAM writing enabled and that the file permissions allow writing. Also verify the NVRAM path in your emulator settings. |
